my function calculate needs to have a directory specified to work. and it won't work if I use "pwd". it only works if I specify the actual directory. how do I get it to work with pwd?
function x=calculate(chan,wd)
.....
end

Is pwd perhaps returning a relative directory rather than an absolute directory?

You can add it to your path.

well, I actually do want it in this case. and for some reason using pwd in the function parameter for directory does not work

So did you make a typo in your question when you wrote:
function x=calculate(chan,wd)
did you actually mean:
function x=calculate(chan,pwd)
?
If you meant the second line, then realise that you should *not* label variables in your function definition to be the same as built-in functions of MATLAB such as "pwd". Instead try something like:
function x = calculate(chan,myDir)
.....
end
And then you can *call* your function with the current directory as follows:
myOutput = calculate(1,pwd);
See the difference?
